Let's divide 740909 by 20
The aim is to understand the frequency of 20 in 740909.

On to step 1:
7 divided by 20 is 0 with a remainder of 7.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 7, we get 7.
Append the next digit (4) from the dividend to 7 and continue with: 74 / 20

Going ahead to step 2:
20 goes into 74 3 times with a remainder of 14.
Use 3 as the next digit of our solution. 
Result so far: 3.0
Subtract 60 from 74 to get 14.
Fetch the next digit (0) from the dividend, attach it to 14 and continue: 140 / 20

On to step 3:
20 can be fit into 140 7 times, resulting in a remainder of 0.
The next digit of our result is 7. 
Result so far: 37.0
If we subtract 140 from 140, we get 0.
Grab the next digit (9) from the dividend, add it to 0, then carry on: 9 / 20

Advancing to step 4:
If we divide 9 by 20, we get 0 and a remainder of 9.
Put 0 as the next digit of the answer. 
Result so far: 370.0
If we take 0 away from 9, we end up with 9.
Grab the next digit (0) from the dividend, add it to 9, then carry on: 90 / 20

Going ahead to step 5:
20 can be fit into 90 4 times, resulting in a remainder of 10.
Write down 4 as next digit of the result. 
Result so far: 3704.0
Subtract 80 from 90 to get 10.
Grab the next digit (9) from the dividend, add it to 10, then carry on: 109 / 20

Advancing to step 6:
109 divided by 20 is 5 with a remainder of 9.
Record the quotient 5 as the next digit in the result. 
Result so far: 37045.0
Subtract 100 from 109 to get 9.
Since there are no more digits in the dividend, we add a zero to the remainder making it 90, and continue the process.

Let's proceed to step 7:
When dividing 90 by 20, we get 4 with a remainder of 10.
Record the quotient 4 as the next digit in the result. 
Result so far: 37045.4
If we subtract 80 from 90, we get 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

On to step 8:
The number 20 fits into 100 5 times, leaving a remainder of 0.
Put 5 as the next digit of the answer. 
Result so far: 37045.45
Subtract 100 from 100 to get 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Moving on to step 9:
0 divided by 20 is 0 with a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 37045.45
Subtract 0 from 0 to get 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

On to step 10:
The number 20 fits into 0 0 times, leaving a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 37045.45
If we subtract 0 from 0, we get 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

The final outcome is 37045.45, with a leftover of 0.0.
